矿石中微量锗的测定,已有文献报导[见冶金分析第1期,8(1981)].此法虽速度快,灵敏度高,但铁有干扰.不适于化探样品中ppm级锗的测定.作者发现在磷酸介质中,有阳离子表面活性剂存在下,锗和水杨基萤光酮能形成灵敏度很高的络合物.本文对水杨基萤光酮—锗—溴化十六烷基三甲铵三元络合物作了系统的研究.实验结果表明:该三元络合 Determination of trace amounts of germanium in ores has been reported in the literature [see Metallurgical Analysis No. 1, 8 (1981)]. Although this method is fast and sensitive, it has interference with iron and is not suitable for the determination of germanium The authors found that germanium and salicylfluorone can form highly sensitive complexes in the presence of a cationic surfactant in a phosphoric acid medium.In this paper, salicylfluorone - germanium - cetyltrimethylammonium bromide Yuan complexes were systematically studied.The experimental results show that the ternary complex
